5 For UHS devices which require tuning, the device tree should have a "cpu_thermal" node which maps to the appropriate thermal zone. This is used to get the temperature of the zone during tuning.

7 Required properties:
8 - compatible: Should be "ti,omap2430-sdhci" for omap2430 controllers
9 Should be "ti,omap3-sdhci" for omap3 controllers
10 Should be "ti,omap4-sdhci" for omap4 and ti81 controllers
11 Should be "ti,omap5-sdhci" for omap5 controllers
12 Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers
13 Should be "ti,k2g-sdhci" for K2G
14 Should be "ti,am335-sdhci" for am335x controllers
15 Should be "ti,am437-sdhci" for am437x controllers
16 - ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1
17 (Not required for K2G).
18 - pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50",
19 "ddr50-rev11", "sdr104-rev11", "ddr50", "sdr104",
20 "ddr_1_8v-rev11", "ddr_1_8v" or "ddr_3_3v", "hs200_1_8v-rev11",
21 "hs200_1_8v",
22 - pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
23
24 Optional properties:
25 - dmas: List of DMA specifiers with the controller specific format as described
26 in the generic DMA client binding. A tx and rx specifier is required.
27 - dma-names: List of DMA request names. These strings correspond 1:1 with the
28 DMA specifiers listed in dmas. The string naming is to be "tx"
29 and "rx" for TX and RX DMA requests, respectively.
30
31 Deprecated properties:
32 - ti,non-removable: Compatible with the generic non-removable property

34 Example:
35 mmc1: mmc@4809c000 {
36 compatible = "ti,dra7-sdhci";
37 reg = <0x4809c000 0x400>;
38 ti,hwmods = "mmc1";
39 bus-width = <4>;
40 vmmc-supply = <&vmmc>; /* phandle to regulator node */
41 dmas = <&sdma 61 &sdma 62>;
42 dma-names = "tx", "rx";
